Petunia plant named ‘Petpo29’

ABSTRACT

A distinct cultivar of  Petunia  plant named ‘Petpo29’, characterized by its compact and outwardly spreading plant habit; freely branching habit; and numerous flowers that are red purple in color.

Botanical classification/cultivar designation: Petunia×hybrida cultivar Petpo29.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name Petpo29.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program is to create new compact and outwardly spreading Petunias with numerous small flowers with attractive flower colors.

The new Petunia originated from a cross-pollination made by the Inventor in September, 2000 of a proprietary Petunia selection identified as X99.2, not patented, as the female, or seed parent, with a proprietary Petunia selection identified as code number X99.23a, not patented, as the male, or pollen parent. The new Petunia was selected as a single plant from the resulting progeny of the cross-pollination by the Inventor in October, 2001, in a controlled environment in Cobbitty, New South Wales, Australia.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Cobbitty, New South Wales, Australia since October, 2001 has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Petpo29 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Petpo29’. These characteristics in combination distinguish ‘Petpo29’ as a new and distinct Petunia cultivar:

-   -   1. Compact and outwardly spreading plant habit.     -   2. Freely branching habit.     -   3. Numerous red purple-colored flowers.

Plants of the new Petunia differ primarily from plants of the female parent in flower color as plants of the female parent selection have lavender-colored flowers. Plants of the new Petunia differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have hot pink-colored flowers with white-colored centers.

Plants of the new Petunia can be compared to plants of the cultivar MP7, disclosed in U.S. Plant Pat. No. 12,819. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Petunia differed from plants of the cultivar MP7 in the following characteristics:

-   -   1. Plants of the new Petunia had larger flowers than plants of         the cultivar MP7.     -   2. Flowers of plants of the new Petunia were brighter in color         than plants of the cultivar MP7.

The photograph at the top of the sheet comprises a close-up view of typical flowers and leaves of ‘Petpo29’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Encinitas, Calif., in an outdoor nursery during the spring with day temperatures about 24° C., night temperatures about 19° C. and light levels about 4,000 foot-candles. Plants were grown for 21 weeks in one-gallon containers with three plants per container. Plants were pinched one time.
